Last week an investor told me some interesting numbers regarding wind energy consent times and number of authorities liaise with. So I decided to make my own research:

The Wind Barriers project also investigated the number of authorities that need to be contacted in each country in order to obtain permission to build onshore. Denmark has the fewest authorities to contact, just five, whereas Greece has the most authorities to contact, with 41. But there is not a direct correlation between the length of time it takes to get permission and the number of authorities that need to be contacted.
The experience in the offshore sector is, so far, more positive. The average time to get the green light is 18 months, much lower than onshore. “A number of countries with offshore wind farms have developed an efficient decision making process for this sector, thereby reducing the complexity for offshore wind developers,” concluded Wilkes.

I have never heard of Pulse Detonation Technology. But GE's working on it to increase the efficiency of gas turbines. Check the interview

Maybe a bit of history but the following numbers worth a look. This is published in June, 2008. Dolar is appreciated since then and commodity prices have collapsed.
Check
this report (Page 11)
"What do all these cost increases mean for the cost of building a new generating
plant?"
"No one knows precisely. It’s difficult to get consistent and trustworthy numbers about plant costs, both because they are commercially sensitive and because the assumptions behind them vary greatly. The numbers reflected on the slide come from a variety of sources and include different assumptions about, for example, location or exactly what facilities are included in the estimate. To take one example: Two recent nuclear procurements in South Carolina and Georgia produced cost estimates of $5,100 and $6,400 per kW, respectively, for the same technology. We have been told that most of the difference may be due to different uses of Allowances for Funds Used during Construction – AFUDC."

It may sound stupid to you, but this is actually true. Too many wind turbines may really slow down earth's rotation, but not to significantly. From
Yahoo Answers :
"
The effect on the Earth's rotation should be less than any effect on the wind. It wouldn't be significant and it might not even be measurable. Besides global climate change from burning coal to generate electricity will effect the Earth far more than the potential lose or gain of a picosecond in a day caused by wind turbines."
You can also check another discussion at
Discovery Community website.
This is the basic problem with generating energy, like
Heisenberg's Uncertainity Principle , when you try to use one kind of technology to harness an innocent energy type, you change other things.
But still, the key point is to have the minimal impact!
